We all know platforms like the Beagleboard, which are cheap hardware platforms which can be used in all sorts of projects. A new entry into this market is Raspberry Pi, a British ARM board which is slated to be released in the fourth quarter of this year. For a mere $25, you'll have a fully-configured ARM-based 1080p-capable mini-motherboard. The device is still in development, and only a few days ago, the alpha version of the board was demonstrated running Quake III.

1) It used an old processor that's no longer supported
2) Supply was always restricted and took months to get the device. And there was NO communication from the vendor.
3) Had bad power supply and the company acknowledged the problem, but offered NO easy solution other than purchase a 27 dollar replacement power supply.
4) Promised the cost would come down to 50 from 99 in a year, but that never happened, instead newer models are more expensive.
5) All the new models with the exception of the latest one still use the ARM5 processor.
6) Unfriendly tech support and lack of "user friendly" developer tools.

If Raspberry Pi can come up with a lowcost alternative, and resolve the issues that plague Sheevaplug, then it would definitely be a success.
